Then this itself is justification for Misbah to put in his papers, no? If the boss is giving you that hint, moving on is the right thing to do.
So why is he being named and shamed for resigning? Even by, in fact absolutely by, what you wrote, that was the right thing to do.
I think I have addressed your main points on my earlier posts but summarising:
If coach absolutely believes that the team given to him or her is totally wrong, and in fact the result of nepotism or some other unsavoury reason, they are within their rights to resign. It’s morally the right thing to do. We don’t know whether that’s why Misbah resigned, but I wouldn’t assume the worst about the man just yet.
Also being asked to leave for the series before a World Cup and them come back only for it (that’s what they say the PCB offered) is a totally ridiculous proposition, and I’m not sure how Wasim thought it would work.
You’re putting the coach in a totally untenable position- how the heck will he prep for the tournament, enforce discipline, when in the interim there’s a new coaching team? It could be said that he’s within his rights to resign.
